Tech Xplore / Entirely new way of making espresso shakes up the coffee world
Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room-temperature water, cutting energy use by up to 75%. That morning coffee kick from a shot of espresso ...
Phys.org / Why birds ignore Newton: New theory could sharpen models of flocks, crowds and cells
Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are ...
Phys.org / Supercomputer illuminates subatomic particle that helps hold matter together
A team of researchers has leveraged a supercomputer at the U.S. Department of Energy's (DOE) Argonne National Laboratory to reveal the internal structure of a pion in unprecedented detail. The findings are published in the ...
Phys.org / Collapsing stars could spawn mini-universes, offering new path to gravastars
Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses ...
Phys.org / 'Black hole stars'—Webb finds strongest evidence yet
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022. Now a particular little red dot's spectrum is helping connect many of the pieces.
Tech Xplore / Human understanding of AI can't keep up with its advancement, researchers say
In a recent editorial published in Science, Microsoft's chief scientific officer, Eric Horvitz, and researcher Robert West from the School of Computer and Communication Sciences at EPFL in Switzerland issue a stark warning ...
Phys.org / Harmonic radar tags reveal how mosquitoes move through fields and parkland
It's an insect everybody loves to hate. Pesky mosquitoes will be out in swarms as the weather warms up across the U.S.—and their bites aren't just itchy. They can transmit pathogens that can cause diseases like West Nile ...
Phys.org / Burned as waste for years, this overlooked plant material is poised to reshape how nylon gets made
Most people have seen nylon listed as a material on their clothing tags, but nylon is used in an array of other products, too, including automotive parts, wire insulation and medical supplies. Unfortunately, one of the building ...
Phys.org / Rare 500-year-old freeze-dried potatoes unearthed at Inca coastal site
Archaeologists digging at an Inca site on the arid coast of southern Peru have unearthed two rare, roughly 500-year-old freeze-dried potatoes. The potatoes are among the only ones found in more than a century and would have ...
Phys.org / Is 'gender gating' the secret to success in online dating?
